YORK, ASSIGNOR ".IO AMERICAN ASSEM- N. Y., A. CORPORATION OF DELAWARE BOOKCOVERING MACHINE Application filed October 7, 1926. :Sera1-No.=140,124.

My invention relates to book or pamphlet covering `machines and more particularly to an improved tipping mechanism wherebyy the flexible covers may be pasted or tipped to the end signatures of separate signature groups immediately after the signaturegathering process has been completed without the necessity of separate handling of the gathered signatures or cover sheets.

The objects of my invention are, among other things, to provide a novel and simplified machine ofthis type by which the cover sheets may be ted in any suitable manner to V`the end signature groups travelling on a is; suitable conveyor in upright .position so that the operation of making the books may `be both automatic and continuous. In the form of my present improvement the books or signature groups may Abe brought automatically from the signature-gatherer or like machine, such as a stitcher, in a horizon-tal plaine and in upright position in conjunction `with an improved tipping' mechanism to prevent the application of surplus paste or glue from the paste-roller on the trip-pressure roller arranged oppositely to such pasteroller in the event that no Cover sheet has been fed to or conveyed along' side of a particular book which is being Vforwarded by the conveyor.V

A further feature of my invention is -to ,provide an improved form of automatic trip mechanism controlled by detectors arranged on either side of the advancing book and located over the paste-pots for moving the trip pressure-roller into and out of operative relation with thepaste-applying roller as each book is advanced by the book conveyor so that the paste may be applied only on they inside ot the cover sheets as required for the separate books and not on the coacting pressure roller in the absence of a cover sheet. A furthe-r feature of Ymy invention is to provide ay novel and improved form of to press the cover sheets against the end signatures of the book after such sheets have received the proper amount of paste along their inner lower margins, such o jaws being actuated in proper timed relation tipping jaws which are designed thereafterl 12 fastened .to the with the'hook conveyor which advances the books through the machine.

By myimprovements the successive books lor lpamphlets travelling in a horizontal direction andin an .upright position may have 'their cover sheets readily applied to the eX- posed end signatures coupled with automatic means for tripping `the tipping or pasting .mechanism on-either side of the book, `'which means are controlled by the absence of a cover sheet on one side or the other. Furtherbbjects and advantages will -be hereinafter described and `then pointed out in the claims. The drawings show the machinefin a preferred form andare illustrative ofthe invention.

In the drawings, Fig. 1 is ageneral top :plan view of a book-covering machine showing my improvements Fig. 2 is a detailed plan view of the trip` mechanism Fig. 2a is a detail viewfof part of Fig. 2 showing lthe trip vpressure-roller latched and lheld away from the pastefroller which is their 1normal position;

Fig. 8 is a plan view of the paste wheels and drive therefor.

Similar numerals refer to similar yparts throughout the several Afigures.

Referring to the drawings, the book conveyor 9 having spacedapart horizontallydisposed lingers 10 extending over the horizontalrace-way ll is driven by the sprocket stub-shaft 13 journalled in the bearing 14 and havingrt-he bevel gear 15 lmeshing with the bevel gear .16 fastened to the `line shaft 'ldriven by the sprocket -18 from any suitable source of power (not shown). Securedto the `race-Way 1-1 are the of the tipping ,jaws

two oppositely disposed vertical guide-plates 19 between which the separate books 2O are advanced along the race-way 11 by the fingers in the direction of the arrow shown in Fig. 1.

The cover sheets 21 which are fed to either side of the books 2O are then conveyed between the guide-plates 19 by the conveyor fingers 10. ln Fig. 1 a cover feeder 22 is shown in dot-andlash outline comprising two sets of feed-wheels 23 (four on each side) by which the cover sheets 21 are separated from suitable piles and brought into parallelism with the end signatures of the books in spaced relationship with the guide-plates 19 to be advanced with the books 2O as shown in Figs. 4 and 7.

Located beneath the book conveyor and race-way 11 are the right and left paste-pots 24 and 25 with their respective paste-applying devices which are alike in construction and are shown in detail in Figs. 7 and 8. A description of one set will suffice for both. Each paste pot has a subjacent hot-water i reservoir 26 provided with the funnel 27 and et-cock 28. The vertically disposed pastewheel 29 is mounted on the spindle 30 and the periphery of the wheel 29 is spaced slightly from the bottom of the paste pot (Fig. 7) The spindle 30 is ournalled in the adjustable sleeve 31 threaded in the bracket 32 and is held in position by the check-nut 33 which bears against the outer end of the bracket 32. The outer end of the sleeve 31 presses firmly against the hub of the drive gear 34 which is rigidly held on the spindle 30 by the clamp nut 35 and locky nut 36. Fastened to the drive-gear 34 are the paste wheel sprockets 37 drive-n by the chains 38 passing over the sprockets 39 keyed to the drive shaft 40 (Fig. 1) journalled in the bearing 41. The drive shaft 40 carries the bevel gear 42 meshing with the bevel gear 43 fast on the line shaft 17. The idler sprocket 44 is rotatably mounted on the stud 45 which is fastened to the idler lever 46 adjustably secured to the-carrier shaft 47 fastened to the side of the water reservoir 26 (Figs. 7 and 8) by which any slack-in the chain 38 is taken up. Running in contact with the peripheral margin of the paste wheel 29 is the horizontally-disposed paste-roller 48 mounted on the stub-shaft 49 to which is fastened the spiral pinion 50 meshing with the spiral gear 51 mounted on the stub-shaft 52 journalled on the cap-bracket 53 to which shaft 52 the drive pinion 54 is keyed and engages the drive gear 34 (Figs. 7 and 8). The paste wheel 29 and the paste-roller 48 are thereby driven in unison at the same peripheral speed; by laterally shifting the sleeve 31 the paste wheel 29 may be moved horizontally in either direction whereby the thickness of the paste film or amount of paste to be applied to the'cover sheets 21 by the paste-roller 48 may resists the action of the cams be regulated to meet the requirements of the job. As shown in Fig. 8 the scraper plate 55 having the slot 56 cut therein through which the paste-wheel 29 revolves causes any ei;- cess paste on the outer side of the wheel 29 to be returned to the paste pots. The pasteroller 48 normally applies paste to the inside of the cover sheets 21 (Fig. 7 the lower margin of which pass between the horizontally-alined paste-rollers 48 and the trip pressure. rollers 57 by which such lower margins of the sheets 21 are held against the paste-rollers 48 to have the required amoumI of paste applied to the inside of the sheets 21 as shown in Fig. 7.

The mechanism for moving the trip pressure-rollers 57 into and out of Contact with the cover sheets 21 and the paste-rollers 48 as each book is advanced by the conveyor 9 automatically controlled by a detector on either side of the book so that rollers 57 may be held away from the paste-rollers 48 should a cover sheet 21 fail to be fed and conveyed along the guide-plates 19 in mutual parallelism with a beok 2() travellingl along the conveyor 9 may be wid-ely varied in construction and operation and is best shown in Figs. 144 and 7 The U-shaped guide channel 58 is horizontally disposed above one side the race-way 11 (Fig. 4) and is supported on the standards 59 so that the ends of conveyor fingers 10 rest in and pass along such channel 58 as shown in Figs. 2 and- 4, Journalled in the bearings 60 secured to the channel 58 is the rock shaft 61 to the forward end of which is fastened the cambracket 62 carrying the detector-hook release cam 63 adapted to be engaged and lifted by each conveyor linger 10 to rock the shaft 61 successively. rlhe opposite end of the rock-shaft 61 carries the cam-bracket 64 with the trip-cam 65 secured on its side (Figs. 2` and 3) which cam 65 is also adapted to be engaged. and lifted by each conveyor finger 10 in the forward movement of the conveyor 9. On the opposite side of the race-way 11 suitable bearing brackets 66 (Fig. 2) are fastened to the under edge of the race-way 11 (Fig. 4) in which brackets the rock-shaft 67 is journalled. The'connecting rod lever 68 is fas- 'ened to the rock-shaft 67 and the end of the lever 68 is pivoted to the connecting rod 69 pinned to the end of the lever 70 secured to the rock-shaft 61. The coil-spring 71 fastened to the collar 72 adjustably secured to the rod 69 by the set-screw 7 3 and to the pin 74 secured to the race-way 11 (Figs. 2 and 3) normally pulls the rod 69 to the left in Fig. 4 and 63 and 65 in rocking the shaft 61 counter-clockwise (Fig. 4).

Each trip pressure-roller 57 and its connecting` mechanism with the cover sheet detectors are substantially alike, and a description of the structural details of one such lill roller 57 and operating mechanism will suffice for both: Referring toI Figs. 2-4, the roller 57 is journalled in the sleeve 75 mounted on the end of the rock-lever 76' adjust-ably securedto the vertical sleeve 77 journalled on the stub-shaft 78 passing through the raceway 11 and rigidly secured thereto bythe nut 79. Also adjustably secured to the sleeve 77 is the rock-lever 80 having` pinned thereto the link 81. The ltrip-operating levers 82 and 83 are each pinned to their respective links 81 and each lever 82 and 83 carries the same form of detector hook-catch 84 on its free end.`

Looking at Figs. 3 and 4 the operating lever 82 is fastened to the upper rock-shaft 61 while the operating lever 83 is secured to the lowerrock-shaft 67 on the opposite side ofthe raceway 11. The rock-arm 85 is adjustably secured to the rock-shaft 61 and the light-coilspring 86 connecting the arm 85 to the lever 82 normally Idraws the arm 85 downwardly against the stop 87 on the lever 82. In like mann-er th-e rock-ar1n 88 is adjust-ably secured to the rock-shaft 67 with the spring 89 connecting the arm 88 to the lever 83 normally draws the arm 88 upwardly against the stopY 91 on the lever 83 by which these arms 85 and 88 are held in yielding connection With the respective stops 87 and 91.

The detectors 92 and 93'on either side of the race-way 11 are pivoted on pins 94-and 95 respectively secured in brackets 96 and 97 respectively mounted on upright standards 98 and 99 respectively aixed to the either side of the race-way 11 (Fig. 4). Fastened to and rocking with the detectors 92 and 93 are the detector hooks 100 and 101 respectively backed by the light springs 102 and 103 fastened to the brackets 96 and 97 which springs 102 and 103 respectively force the tips of thedetectors 92 and 93 against the cover sheets 21 as they pass sidewise along the inclined plates 104 and 105 fastened to the guide plates 19, such plates being formed U-shaped in crosssection as shown in Fig. 4. The detector hooks 100 and 101 are adaptedto coact with the catches 84 secured to the operating levers 82 and 83 respectively. Fig. 2a shows the normal coacting engagement of catch 84 and? hook 100 with the detector 92 resting within the plate 104 in the absence of a cover sheet' 21 and the trip pressure-roller 57' held away from the paste roller 48. Figs. 2 and 4showH the detector hooks 100 and 101 released'from the catches 84 due to the cover sheets 21 holding the detector tips out oflthegrooves in the inclined plates 104-and 105 so as to bring the trip pressure-rollers57 against the paste rollers 48 to apply paste Vto the inside lower. margins of the sheets as the books20 pass along the raised runway 106 extending along the race-way 11 between the guide-plates 19 as shown in Fig. 7.

Such tipping' jaws and theiroperating mechanism are best shown in Figs. '1,.5 and 6. Secured to the undersideofthe race-wayll is the,` transverse bracket, 107 which Sup-r .1 ports the depending bearings 108-and1109fin 80 which' the horizontal shafts 110 and 111 ar( journalled. Theshafts 110-and;111 carry the sprockets 112: and 113 respectively 4over which passes the. sprocket chain 114. Thegs idler sprocket `115 iournall'ed onthepin 116 adjustably mounted on the vertical stub-shaft 117 secured-to the bracket'107 bears on the under side of thefchain 114 to take up any slackin such chain 1141:(Fig. 5)'.

tively which engage the cam surfaces 162 and L163 ofthe tipping jaw 150. The jaws 134 and 150 have a rotary niovementin conjunction with their mutualreciprocations as the four disks 132, 133 and 148, 1494 are rotated,

sincethe pins holding the cam-rollers 156, 157 and 160, 161 respectively are connected by straps (Fig. 6) which cause the jaws 134 and 150 to describe an orbital path relatively to each other as they are reciprocated. When the disks 132, 133 and 148, 149 are rotated in unison by the mechanism just described, the two tipping jaws 134 and 150 are reciprocated in unison to press the cover sheets 21 of the book 20 passing along the race-way 11 between these jaws with a gradually increasing vpressure after which thel jaws 134 .and 150 release the book when the revolutions of these four disks withdraw the two jaws so that they no longer press against previously in contact with the jaws 134 and 150 as has just been described.

After the books 2() have travelled along the race-way 11 beyond the tipping jaws 134 and 150, they are advanced between the converging conveyor chains Y164 Vand 165 which pass around the sprockets 166 and'167 respectively driven in the direction of the y arrows shown in dot and dash outline in Fig. 1. Such books are carried byA these chains 164 and 165 in upright position out of the machine. l

In operation the successive books 20 enter the race-way. 11 from the right inFig. 1 and the cover sheets 21 are vseparated and brought in alinement with the end signatures Y of the books between the guide plates 19 by the cover sheet-feeder 22 and between the veyor 9. As the spaced-apart conveyor fingers 10 on the conconveyor 9 advances in the direction of the arrow both books 20 and roller 48 and trip pressure-roller 57 on each side of the machine are held separated as shown in Fig. 2a. However the end Iof the conveyor-finger v10 in its forward movement engages the detector-hook release camv63 which rocks the shaft' 61 in a counter-clock -wise direction (Fig. 4) thereby disengaging the catches 84 ofthe trip-operating le,

vers 82 and 83 from the detector hooks 100 and 101, the various parts assuming the out of their respective groove plates 104 and 105 by the cover sheets; the conveyor finger 10 is shown as ust releasing the cain 63. In such positions the two paste-rollers 48 apply the film of paste on their peripheries to the inner lower margins of the twocover sheets 21 (Fig. 7) which are held against the rollers 48 by the pressure-rollers 57. However should a inisfeed of a cover sheet 21 occur on either side of the book 20, the tip of the detectors 92 or 93 would be forced into the grooved plate 104 or 105respectively by the springs 102 or 103 in the absence of a sheet, which would bring the parts into the positionsshown in Fig. 2@l with the particular presure-roller 57 held out of contact of its coacting paste-roller 48 and no paste would be transferred from the roller48 ont' the periphery of the pressure-roller 57. Then the conveyor fingers 10 in their for ward travel engage the trip cam 65, the shaft 61 is rocked so as to allow the coil spring 71 to restore the connecting mechanism shown more particularly in Figs. 2, 3 and 4 into its normal position, the trip-operating' levers 82 and 83, bythe yielding connection aforded `are advanced along the race-way11.

Thereafter the books 20 and the thereto pasted cover sheets 21 are forwarded between the coacting horizontally-movable tipping jaws 134 and 150 which in turn force4 thecover sheets 21 in firm contactwith the book 20 with a gradually increasing pressure that is thereafter relaxed as the rotating disks 132, 133 and 148, 149 continue theirI revolutio-ns as has been hereiiibefore de? scribed. VThe books with their cover sheets tipped to the end signatures of the book arezthen brought between the conveyor chains 164 and 165 which carry the books in up-- right position out of the machine.
